1. What is the Forklift Lift Capacity Formula?

The forklift lift capacity formula calculates the actual capacity of a forklift when the load center differs from the rated load center. It's crucial for safe forklift operation and preventing tip-overs.

2. How Does the Calculator Work?

The calculator uses the forklift capacity formula:

Where:

• \( Rated\ Capacity \) — Manufacturer's rated capacity (lb)
• \( Rated\ Load\ Center \) — Manufacturer's specified load center distance (inches)
• \( Actual\ Load\ Center \) — Actual load center distance of your load (inches)

Explanation: The formula accounts for the reduced capacity when loads extend beyond the rated load center due to increased torque on the forklift.

3. Importance of Load Center Calculation

Details: Correct capacity calculation prevents forklift tip-overs, maintains stability, and ensures safe operation within the forklift's design limits.

4. Using the Calculator

Tips: Enter the forklift's rated capacity, rated load center (typically 24 inches for standard forks), and the actual load center of your specific load. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What happens if my actual load center exceeds the rated?
A: The forklift's actual capacity decreases proportionally. Exceeding capacity can cause tip-overs or structural damage.

Q2: Where do I find the rated capacity and load center?
A: These are specified on the forklift's data plate, usually located near the operator's compartment.

Q3: Does this calculation apply to all forklifts?
A: Yes, but specialized forklifts may have additional factors to consider. Always consult the manufacturer's specifications.

Q4: What safety margin should I use?
A: Industry standard is to never exceed 80% of the calculated capacity for added safety.

Q5: How does load height affect capacity?
A: Higher lifts further reduce capacity. Some forklifts provide load charts showing capacity at different heights.
